In the 576th year of the New Calendar, several large steel ships floated above the vast sea.

Next to a huge ship, a small submarine was slowly lowering, and someone was talking on the side of the ship.

"Dr. Strong, this is the most advanced submarine in the Federation so far, able to dive into the deep sea more than 10,000 meters. I hope you can shrink!"

A middle-aged man in a suit and tie looked at the sea and spoke.

"Looking for the prehistoric secluded civilization and proving its existence to the world is my lifelong wish. I have consulted all the documents and materials, combined with the legends circulating around the world, the last city of Atlanta, the city of Atlanta, has a great probability that it will be under this deep sea!"

Dr. Strong is an old man with white hair and beard, but he still looks in good spirits and says with great enthusiasm, his eyes full of anticipation.

"Teacher, it's already done!"

At this time, the submarine finally entered the water, and several young men and women looked up and shouted.

"Here you come!"

Dr. Strong responded, said goodbye to the middle-aged man, and left in a hurry.

Soon he took his men into the submarine and gradually fell into the deep sea and disappeared without a trace.

"You actually put your hope on these legends, and in my opinion it's just a waste of time and resources."

At this time, a middle-aged man walked out of the cabin behind him and spoke.

"The legend may not be all false. The situation is getting worse and worse now. It is better to do something than not."

The middle-aged man sighed.

"I hope there is good news!"

......

Inside the submarine.

The height continued to decline, and the surrounding sea water also became dark from brightness, and then it was pitch black. Only some marine creatures emitted a glimmer of light, curiously surrounding the submarine, looking at this big guy I had never seen before.

The space inside the submarine was narrow and the air was turbid, but Dr. Strong and his students were used to it. Two bright white lampposts were turned on, and some marine creatures suddenly fled in panic.

Three thousand meters.

Five thousand meters.

Ten thousand meters.

This is already the extreme depth of the submarine, and the surroundings have become deserted and cold. The occasionally wandering marine creatures are also weird and strange in shape.

"It's not the end yet!"

But the expected lost city of Atlan did not appear in front of them at all, and the few people were suddenly a little panicked.

"Continue diving!"

Dr. Strong had a serious expression and spoke coldly.

"There will be dangers at any time if it dives..."

A student whispered, but no one dared to refute him, so he could only control the submarine to continue to descend. Suddenly, something passed through the observation mirror.

"Look at that side!"

Accompanied by the excitement, the eyes of several people gathered over, and the submarine lamp post moved with a few tall stone pillars standing with blurry patterns on them, with regular and consistent shapes, which were obviously not formed naturally.

The lamppost continues to move forward, and the next scene makes everyone's breathing stagnate.

I saw endless urban waste, tall buildings, broken walls, collapsed buildings, and some foundations that were corroded by sea water and left only traces appeared. As the lamp posts swept across, some marine creatures rushed out from inside in panic.

"Lost City, Atlan!"

Dr. Strong murmured to himself, his eyes bursting with unprecedented excitement.

"We finally found that prehistoric civilization does exist, and this is the best evidence!"

"We succeeded!"

Several students also hugged each other, with smiles on their faces.

For Dr. Strong, this is a name in history, but for them, it seems that they have seen money, honor, etc. coming, how can they be unhappy?

"Continue to move forward, we need to find some specimens to bring them up!"

Dr. Strong waved his hand and the submarine crossed the city's ruins and headed towards the central area.

On the way, he also explained to his students: "Although the Youhai Civilization is called a civilization, according to the information, there is actually only one core of their entire civilization, that is, Atlanta City, more than 90% of the legends point to this ancient city!"

"Legendary: The Youhai Civilization used to live on land, but because of the disaster, the land where it was located sank into the sea, which became a marine civilization. Later, the city of Atlanta was destroyed, and the entire civilization was destroyed!"

"Teacher, how did Atlanta destroy it?"

Some students wondered.

"In legend, after the city of Atlanta sank into the bottom of the sea, it awakened the monsters in the deep sea. It was born with the world, and its existence since ancient times finally destroyed the entire city!"

Dr. Strong sighed: "Although our aircraft has reached space, we still know very little about the ocean under our feet, and no one knows how many unknown secrets are hidden in it."

He is worthy of being an expert in Atlanta. Under his guidance, the submarine sailed towards the city center, and countless urban buildings below became increasingly broken, with ruins everywhere, and almost none of them were intact.

"It's like coming to the battlefield. Even after countless years, you can still see the tragedy at that time!"

A student swallowed and said.

"The core of Atlanta City is a temple, which is usually the tallest and most magnificent building in the center of the city, with a pyramid. If you look carefully, even if it is destroyed, there should be still remains of wreckage!"

Dr. Strong Road.

Several students suddenly widened their eyes and tried hard to find them.

"What is that?"

Suddenly, someone screamed in shock, pointing to a place in the city, showing a look of horror.

The others turned to look, but found that it turned out to be a huge corpse, which stretched across the city, and the bones turned into fossils. Countless buildings under them collapsed, and the one facing the front happened to be a broken pyramid!

Even though they had been dead for a while, everyone could still feel the indescribable power and had a moment of absent speech.

"At least, this must be three or four hundred meters!"

You should know that the largest creature discovered by humans, the whales living in the ocean, are only a hundred meters long.

"Don't worry about that much, go and see what the temple is like!"

Dr. Strong calmed down and manipulated the submarine to advance towards the pyramid. Only then did he realize that the pyramid was extremely broken and almost leaking from all sides. It was a miracle that it had not collapsed yet.

"Get closer, get closer!"

Dr. Strong murmured to himself, the submarine gradually approached the pyramid and finally even drilled into one of the gaps.

The inside and outside of the pyramid are as broken as the outside, but the space is very large, and the submarine is very slow to release. When we arrived at a hall, the lamp post suddenly shone on something and shined.

"What is that?"
